One of the nation's largest and oldest children's hospitals is cracking down on parents who bring their kids herbs, extracts or other dietary supplements.

In what it describes as a break from other hospitals, the Children's Hospital of Philadelphia, or CHOP, last month removed most dietary supplements from its list of approved medicines, and established new policies for administering them.

A mashup of innovation and old-school hacking (though none of the participants was bent on doing harm, we're assured), the goal of the competition was to improve the nation's health system and help people navigate the complexities of the Affordable Care Act.

The McDonald's at the Truman Medical Centers' main campus in Kansas City, Mo., has closed, ending an epic, two-decade stint inside the hospital and making it the fifth health facility in the past few years to give the Big Mac the boot.

Immediately after last week's election, Missouri Gov. Jay Nixon announced the state would not be setting up its own health insurance exchange. Next door in Kansas, Gov. Sam Brownback announced that Kansas will have no involvement in running a state exchange either. The moves open the door for increased federal involvement in health care in staunchly Republican territory.

On one side of a wall inside the Truman Medical Center cafeteria in Kansas City, Missouri, the menu features low-calorie, low-fat and low-sodium meals. On the other side of the wall is a McDonald's, featuring hamburgers and french fries.

While the law goes before the Supreme Court this week, health providers are already gearing up for a surge in patients with insurance.

Around the country, hundreds of free clinics have been established over the past 50 years to treat patients like Patsy Duarte.
